Embodiment Construction

[0021] Such as Figure 1 to Figure 8 As shown, an annular header eccentric hole adjustable drilling platform device includes an angle bracket 1 welded by section steel. The angle bracket 1 includes a horizontal plate and a vertical plate, and one end of the horizontal plate is welded vertically to one end of the vertical plate. , the other end of the horizontal plate and the other end of the vertical plate are welded with inclined plates connected at a certain angle to the horizontal plate and the vertical plate respectively. In this embodiment, the angle between the inclined plate and the horizontal plate is 30 degrees, and the module The bottom end of the bottom plate 21 of the type roller frame 2 is fixedly installed on the top end face of the inclined plate; at least three modular roller frames 2 are installed on the angle bracket 1, and five modular roller frames 2 are installed in this embodiment. The roller frame 2 includes horizontal rollers 22 and two sets of vertical...

Abstract

The invention provides an adjustable drilling platform device for a ring header eccentric hole. The positioning angle of the eccentric hole can be ensured accurately, the safety and reliability rare improved greatly, usage requirements of ring headers with different diameters can be met, simple and convenient installation and adjustment are achieved, the universality is good, and actual productionand use can be met well. The adjustable drilling platform device comprises an angle bracket formed by welding profile steel, and the angle bracket is provided with at least three modular roller frames with adjustable positions. The modular roller frames comprise horizontally-arranged rollers and vertically-arranged rollers which are fixed on a bottom plate, the horizontally-arranged rollers are installed horizontally at the middle position of the top of the bottom plate, and the vertically-arranged rollers are fixed on a vertically-arranged roller supporting seat perpendicular to the bottom plate.

Description

technical field [0001] The invention relates to the technical field of drilling tooling for annular headers in boiler manufacturing, in particular to an adjustable drilling platform device for eccentric holes of annular headers. Background technique [0002] In the boiler manufacturing process, especially circulating fluidized bed boilers, there are large-scale cyclone separators, and the upper and lower ends of the cyclone separators need to be connected with matching annular headers. It is necessary to open pipe joint holes in the circumferential direction of the annular header. Due to design requirements, some boilers need to open holes along the circumferential direction at a certain angle away from the center of the annular header, and the number of eccentric holes in the annular header is not only large , the accuracy of the angle is relatively high, and it also needs to meet the drilling requirements of ring headers with different diameters. [0003] In the prior art...
